Update Rules Syntax
I am checking update rules. what we are doing getting some fields from one ODS and storing in variables and these variables are used to update some other ODS.
for this purpose we are using select single * from xxx(ODS Name). but we want one 1 or two fields from the ODS. if i write select single yyy(field name) from xxx(ODS name) is there any performance improvement.
Can any one please suggest me how can i improve performance of Update rules and transfer rules.
